ABSTRACT

A louver module includes a louver module body that extends in a length-wise direction, a width-wise direction and a height-wise direction such that the length-wise direction, the width wise-direction and the height wise direction are oriented perpendicularly relative to one another. The louver module body has a plurality of air passageways extending through the louver module body generally in the width-wise direction. Each one of the plurality of air passageways has a serpentine configuration.

FIELD OF THE INVENTION

The present invention is related to a louver module. More particularly,the present invention is related to a louver module having a matrix ofserpentine-shaped air passageways.

BACKGROUND OF THE INVENTION

Louver modules are commonly known in the art and are used for a varietyof applications such as for cooling towers, closed circuit coolers andevaporative condensers. One example of a commercial application forlouver modules is employed in a conventional heat exchanger 100 asdescribed in U.S. Pat. No. 6,923,250 and as illustrated in FIGS. 1-6.The conventional heat exchanger 100 includes a cabinet 102 that housesan exhaust fan 104, a manifold 106, a direct heat exchanger medium 108and a plurality of conventional louver modules 110. As is commonly knownin the art, the manifold 106 supplies water via spray nozzles 112 in aspray form to the direct heat exchanger medium 108 while the exhaust fandraws air represented by the solid single-line arrows from outside thecabinet 102 though the louver modules 110. As the water flows downwardlyalong the direct heat exchanger medium 108 and as air is drawn upwardlyby the exhaust fan 104 through the direct heat exchanger medium 108,heat is effectively exchanged between the flowing water and the movingair. After heat has been exchanged, the water drips into and accumulatesin a water basin 113.

As shown in FIGS. 2-5, each louver module 110 forms a plurality of airpassageways 116 having trapezoidal cross-sectional configurationsdefined between respective louver walls 118. As a shown in FIG. 4, eachair passageway 116 is bent at an approximate central location X in asideways V-shape as viewed in plan view as each air passageway 116extends from outside and into the cabinet 102. Although a bent airpassageway 116 introduces a slight pressure drop of the air pressure asair enters into the cabinet, there are advantages of having bent airpassageways.

With reference to FIG. 4, sunlight represented by the dashed arrow SLcannot readily enter into the cabinet 102 as a result of bent airpassageways. Significantly reducing the amount of sunlight that entersinto the cabinet through the louver modules 110 retards the growth ofalgae, mold or microorganisms in the water basin 113. It is commonlyknown in the art of heat exchangers that growth of algae, mold ormicroorganisms is promoted by sunlight and prevention of such growthreduces maintenance cost of the heat exchanger. Furthermore, as shown inFIG. 5, the air passageways 116 are angled downwardly relative from theoutside of the cabinet 102 to the inside of the cabinet 102 at an angleZ of approximately 100 in a width-wise direction extending parallel to ahorizontal axis H. This downwardly orientation of the air passageways116 into the cabinet 102 prevents or reduces an amount of watersplashing out of the heat exchanger 100 and also allows any water thatmay have accumulated in the air passageway or on the backside of thelouver module to drain back into the water basin.

However, there is a drawback in providing a louver module 110 havingbent air passageways 116 as described above. Although bent airpassageways 116 are effective in retarding the growth of algae, mold andmicroorganisms, the heat exchanger efficiency of such heat exchanger isreduced. As shown in FIG. 6, it has been observed in a laboratorysetting that as air represented by the solid-line arrows enters into thecabinet 102 through the louver modules 110, the bent air passageways 116cause the air above the water basin 113 and below the direct heatexchanger medium 108 to swirl (represented by solid-line arcuate arrows)in somewhat of a circular fashion. Such swirling of air inside thecabinet 102 above the water basin 113 and below the direct heatexchanger medium 108 causes poor air distribution within the cabinet anda reduction in air pressure in at least some areas below the direct heatexchanger medium 108 negatively impacting the flow of air over the waterflowing downwardly on the direct heat exchanger medium 108 at theseareas. It is desirable to maintain uniform air and water distributionacross the heat exchanger medium to ensure optimal thermal efficiency.

Furthermore, a shown in FIGS. 4 and 6, the air enters into the cabinet102 at an air entry angle Y relative to the horizontal axis H. It hasbeen observed in the laboratory that the air entry angle Y at which theair enters the cabinet 102 contributes to this swirling effect.

It would be advantageous to provide a louver module having a pluralityof air passageways that inhibit sunlight from entering into the waterbasin of a heat exchanger cabinet and simultaneously direct air to enterinto the cabinet generally parallel to the width-wise direction of thelouver module. It would be beneficial to provide a louver module havinga plurality of air passageways that inhibits or eliminates air swirlinside the cabinet. The present invention provides this advantage andthis benefit.

OBJECTS AND SUMMARY OF THE INVENTION

It is an object of the invention to provide a louver module with aplurality of air passageways that inhibit sunlight from entering intothe cabinet of a heat exchanger and simultaneously permit air to enterinto the cabinet generally parallel to the width-wise direction of thelouver module.

It is another object of the invention to provide a louver module with aplurality of air passageways that inhibit sunlight from entering intothe cabinet of a heat exchanger and simultaneously inhibit or eliminateair swirl inside the cabinet.

Accordingly, a louver module of the present invention includes a louvermodule body that extends in a length-wise direction, a width-wisedirection and a height-wise direction such that the length-wisedirection, the width wise-direction and the height wise direction areoriented perpendicularly relative to one another. The louver module bodyhas a plurality of air passageways extending through the louver modulebody generally in the width-wise direction. Each one of the plurality ofair passageways has a serpentine configuration.

These objects and other advantages of the present invention will bebetter appreciated in view of the detailed description of the exemplaryembodiments of the present invention with reference to the accompanyingdrawings, in which:

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

Hereinafter, embodiments of the present invention will be described withreference to the attached drawings. The structural components common tothose of the prior art and the structural components common torespective embodiments of the present invention will be represented bythe same symbols and repeated description thereof will be omitted.

As generally introduced in FIGS. 7-14, a louver module 10 of a firstembodiment of the present invention includes a louver module body 12that extends in a length-wise direction L with a length 1, a width-wisedirection W with a width w and a height-wise direction H with a heighth. Specifically with reference to FIG. 7, the length-wise direction L,the width wise-direction W and the height-wise direction H are orientedperpendicularly relative to one another such that the length-wisedirection L and the width-wise direction W define a length-width planePLW, the height-wise direction H and the width-wise direction L define aheight-width plane PHW and the height-wise direction H and thelength-wise direction L define a height-length plane PHL. As best shownin FIGS. 8 and 9, the louver module body 12 has a plurality of airpassageways 14 extending through the louver module body 12 generally inthe width-wise direction W. As best shown in FIGS. 8 and 14, each one ofthe plurality of air passageways 14 has a serpentine configuration.Although not by way of limitation, for the first embodiment of thelouver module 10 of the present invention, the serpentine configurationresembles a sinusoidal configuration in a form of a generally standardnormal distribution curve as viewed in plan view as particularly shownin FIGS. 10 and 14.

With reference to FIGS. 7-9, the plurality of air passageways 14 form amatrix having a plurality of columns of air passageways 14 and aplurality of rows of air passageways. The plurality of columns of airpassageways 14 are arranged in a juxtaposed manner and extendrectilinearly in the height-wise direction H and the plurality of rowsare arranged in a juxtaposed manner and extend rectilinearly in thelength-wise direction L.

In FIGS. 7-10 and 12, the louver module body 12 includes a plurality offirst panel members 16 and a plurality of second panel members 18. Asdescribed in more detail below, the plurality of first panel members 16fabricated from plastic resins or any other thin formable material suchas composites or metals are interspersed with the plurality of secondpanel members 18 fabricated from plastic resins or any other thinformable material such as composites or metals in an alternatingfashion. At least one of the first panel members 16 is disposed betweenand connected to adjacent ones of the second panel members 18 in afacially opposed manner and at least one of the second panel members 18is disposed between and connected to adjacent ones of the first panelmembers 16 in a facially opposed manner to form a stacked arrangement ofalternating ones of the first and second panel members as shown in FIGS.7-10. The first and second panel members 16 and 18 are connectedtogether in a conventional manner such as by employing an adhesivealthough other conventional methods could be used to fabricate thelouver module 10 of the present invention such as by mechanical bonding,plastic welding, ultrasonic bonding, RF bonding, fusion bonding and thelike. As illustrated in FIGS. 8, 10 and 12, each one of the plurality offirst panel members 16 has a generally sinusoidal configuration asviewed in the length-width plane PLW and each one of the plurality ofsecond panel members 18 has a generally sinusoidal configuration asviewed in the length-width plane PLW.

As best shown in FIG. 9 and as shown in FIGS. 8, 11 and 12, theplurality of second panel members 18 include a plurality of foldedsections 18 a with individual ones of the folded sections 18 a extendinggenerally in the width-wise direction W (best shown in FIG. 11). Thefolded sections 18 a are folded along a line extending to and betweenthe inlet opening and the outlet opening.

As shown in FIGS. 7, 8 and 11, the louver module body 12 has an exteriorside 12 a and an interior side 12 b that is disposed opposite theexterior side 12 a. In FIGS. 11, 13 and 14, each one of the plurality ofair passageways 14 has an inlet opening 12 c positioned on the exteriorside 12 a and an outlet opening 12 d positioned on the interior side.The inlet opening 12 c directs air into respective ones of the pluralityof air passageways 14 and the outlet opening 12 d directs air out of therespective ones of the plurality of air passageways 14.

In this first embodiment of the louver module 10, it is preferred thatthe configuration of the inlet opening 12 c and the outlet opening 12 drepresents the shape of the cross-section of the entire air passageway14. In this instance, the cross-sectional configuration of the firstexemplary embodiment of the louver module 10 of the present invention issubstantially square. One skilled in the art would appreciate that asquare is also a rectangle. Although not by way of limitation, it ispreferred that the cross-sectional configuration of each one of theplurality of air passageways 14 is substantially uniform throughout theair passageway 14, i.e., from the inlet opening 12 c through the outletopening 12 d.

As best illustrated in FIGS. 13 and 14, the serpentine configurationincludes a first curved air passageway portion 14 a, a second curved airpassageway portion 14 b and an intermediate curved air passagewayportion 14 c. The intermediate curved air passageway portion 14 c isdisposed between and is in fluid communication with the first and secondcurved air passageway portions 14 a and 14 b respectively. Forexplanation purposes only for the first exemplary embodiment of thelouver module 10 of the present invention, an imaginary reference lineIRL shown in FIGS. 8, 13 and 14 extends from and between the inlet andoutlet opening 12 c and 12 d making point-contact at the respectiveinlet and outlet openings 12 c and 12 d as viewed in the length-widthplane PLW. The imaginary reference line IRL extends parallel to thewidth-wise direction W for the first exemplary embodiment of louvermodule 10 of the invention. The first and second curved air passagewayportions 14 a and 14 b are curved in a first direction while theintermediate curved air passageway portion 14 c is curved in a seconddirection generally opposite the first radial direction. Moreparticularly, as shown in FIG. 14, the intermediate curved airpassageway portion 14 c faces the imaginary reference line IRL while thefirst and second curved air passageway portions 14 a and 14 brespectively faces generally away from the imaginary reference line IRL.In other words, the first and second curved air passageway portions 14 aand 14 b are curved generally away from the imaginary reference line IRLwhile the intermediate curved air passageway portion 14 c is curvedtowards the imaginary reference line IRL.

Furthermore, with reference to FIGS. 8, 10, 13 and 14, the first, secondand intermediate curved air passageway portions 14 a, 14 b and 14 ccurve in the length-wise direction L away from and relative to theimaginary reference line IRL. Note also in FIGS. 13 and 14 that an apexpoint AP is disposed apart from the imaginary reference line at adistance Dx. In FIG. 13, the air passageway 14 has a passageway openingwidth POW that extends in the length-wise direction L. Although not byway of limitation but for example only, the distance Dx is equal to thepassageway opening width POW. However, one of ordinary skill in the artwould appreciate that the distance Dx might be larger than thepassageway opening width POW or might be smaller than the passagewayopening width POW so long as sunlight SL can be inhibited from enteringinto the cabinet 102 to prevent the sunlight from impinging upon thewater in the water basin 113. However, as illustrated in FIG. 14,sunlight SL represented by the dashed arrow enters into the inletopening 12 c and impinges adjacent the apex point AP thereby thesunlight is effectively blocked from entering into the water basin 113.One of ordinary skill in the art would appreciate that minimizing theamount of sunlight that enters into the water basin 113 would also beacceptable without departing from the spirit of the invention.

FIG. 15 is an x-y graph illustrating a multiple order polynomial.Although not by way of limitation but by example only, the multipleorder polynomial is represented by the following equation:

y=−0.0701x ⁵+0.7918x ⁴−3.1513x ³+5.048x ²−2.6668x+0.5818.

However, the inventors believe that the multiple order polynomial is atleast a fourth order multiple order polynomial and that the constantspreceding each “x” variable can change without departing from the spiritof the invention.

A skilled artisan would comprehend that the illustrated multiple orderpolynominal is only partially represented in FIG. 15 and is notillustrated completely accurately or precisely to scale. However, inFIGS. 13, 14 and 15, the serpentine configuration for the firstexemplary embodiment of the louver module 10 of the present invention isdefined by a multiple order polynomial segment MOPS1 of the multipleorder polynomial. In other words, the multiple order polynomial segmentMOPS1 mathematically represents the air passageway configuration of thefirst exemplary embodiment of the louver module 10 of present invention.This multiple order polynomial segment MOPS1 was derived from acomputational fluid dynamics analysis software program in order tominimize pressure loss across the air passageway 14. Since the airpassageway 14 has, in general terms, three bends, it was necessary toemploy computational fluid dynamics analysis software to determine theserpentine configuration of the air passageway 14 in order to minimizethe pressure loss across the air passageway 14 as air flowedtherethrough.

Also, note that the inlet opening 12 c and the outlet opening 12 d makepoint-contact at respective points c and d along the imaginary referenceline IRL. A skilled artisan would comprehend that the inlet opening 12 cand the outlet opening 12 d would facially oppose one another if theserpentine configuration of the air passageway 14 was hypotheticallystraightened.

A second exemplary embodiment of a louver module 210 of the presentinvention is introduced in FIGS. 16-20. The second exemplary embodimentof the louver module 210 is substantially similar to the first exemplaryembodiment of the louver module 10 except for the orientation of theserpentine air passageways 14. As best shown in FIGS. 16, 17, 18 and 20,each one of the plurality of air passageways is oriented at a downwardlyangle S. The downwardly angle S is in an approximate range of 1° to 45°as viewed in the height-width plane PHW. However, it is preferred thatthe approximate range is approximately between 20° and 30°. Morespecifically, each serpentine air passageway 14 extends downwardly asviewed from the respective inlet openings 12 c to the respective outletopenings 12 d as best shown in FIG. 20 along the imaginary referenceline IRL. As best shown in FIG. 20, each one of the outlet openings 12 dis positioned on the interior side 12 b and each one of the inletopenings 12 c positioned on the exterior side 12 a and is disposed aboverespective ones of the outlet openings 12 d as viewed in theheight-width plane PHW.

The third exemplary embodiment of a louver module 310 of the presentinvention is introduced in FIGS. 21-25. The third exemplary embodimentof the louver module 310 is substantially similar to the secondexemplary embodiment of the louver module 210 except for thecross-sectional configuration of the serpentine air passageways 14.Specifically, each one of the plurality of air passageways 14 has across-sectional configuration in a shape of a trapezoid as best shown inFIGS. 22 and 23.

A fourth exemplary embodiment of a louver module 410 of the presentinvention is shown in FIG. 26. The fourth exemplary embodiment of thelouver module 410 is substantially similar to the second exemplaryembodiment of the louver module 210 except for the cross-sectionalconfiguration of the serpentine air passageways 14. As shown in FIG. 26,each one of the plurality of air passageways 14 has a cross-sectionalconfiguration in a shape of a triangle.

A fifth exemplary embodiment of a louver module 510 of the presentinvention is shown in FIG. 27. The fifth exemplary embodiment of thelouver module 510 is substantially similar to the second exemplaryembodiment of the louver module 210 except for the cross-sectionalconfiguration of the serpentine air passageways 14. As shown in FIG. 27,each one of the plurality of air passageways 14 has a cross-sectionalconfiguration in a shape of a standard normal distribution curve.

Although not by way of limitation, all of the above exemplaryembodiments of the present invention might have air passageways that, asviewed in plan view, are slightly modified. Examples of theseslightly-modified air passageways are illustrated in FIGS. 28-31.

In FIG. 28, the first curved air passageway portion 14 a is truncated toa first truncated curved air passageway portion 14 a 1 to form an airpassageway 114. As a result, note that the inlet opening 12 c does notmake point contact along the imaginary reference line IRL but isdisposed apart from the imaginary reference line IRL a distance Dy inthe length-wise direction L. A skilled artisan would comprehend that theinlet opening 12 c and the outlet opening 12 d would be consideredoffset from one another in the length-wise direction if the serpentineconfiguration of the air passageway 114 was hypothetically straightened.Also, note that sunlight SL is inhibited from entering into the waterbasin 113 even though the first truncated curved air passage portion 14a 1 is shorter than the first curved air passageway portion 14 a.

In FIG. 29, the serpentine configuration is similar to the serpentineconfiguration of the air passageway 14 in FIG. 14. However, an airpassageway 214 includes a first straight air passageway portion 14 dconnected directly to and in fluid communication with the first curvedair passageway portion 14 a as an air inlet into the louver module bodyand a second straight air passageway portion 14 e connected directly toand in fluid communication with the second curved air passageway portion14 b as an air outlet out of the louver module body. One of ordinaryskill in the art would comprehend that the first straight air passagewayportion 14 d would cause air flowing into the louver module to flowparallel to the imaginary reference line IRL and the second straight airpassageway portion 14 e would cause air to flow from the louver moduleparallel to the imaginary reference line IRL. Thus, air from the louvermodule would flow generally parallel to the width-wise direction of thelouver module into the water basin area.

In FIG. 30, the serpentine configuration is similar to the serpentineconfiguration of the air passageway 114 in FIG. 28 except that an airpassageway 314 includes the second straight air passageway portion 14 econnected directly to and in fluid communication with the second curvedair passageway portion 14 b as an air outlet out of the louver modulebody.

In FIG. 31, the serpentine configuration is similar to the serpentineconfiguration of the air passageway 314 in FIG. 30 except that an airpassageway 414 includes the first straight air passageway portion 14 dconnected directly to and in fluid communication with the firsttruncated curved air passageway portion 14 a 1 as an air inlet into thelouver module body and the second straight air passageway portion 14 econnected directly to and in fluid communication with the second curvedair passageway portion 14 b as an air outlet out of the louver modulebody.

In view of FIGS. 28-31, it would be appreciated by a skilled artisanthat the serpentine configuration can include at least a first straightair passageway portion 14 d connected directly to and in fluidcommunication with the first curved air passageway portion 14 a or withthe first truncated curved air passageway portion 14 a 1 as the airinlet into the louver module body 12 and a second straight airpassageway portion 14 e connected directly to and in fluid communicationwith the second curved air passageway portion 14 b as an air outlet outof the louver module body 12.

As illustrated in FIG. 32, the louver module of the present inventionhas a plurality of air passageways that inhibit sunlight from enteringinto the cabinet of a heat exchanger and simultaneously permit air toenter into the cabinet generally parallel to the width-wise direction ofthe louver and maintaining a low pressure loss across the louver module.As a result, it is theorized that air swirl is now inhibited or eveneliminated as a result of the configuration of the air passageways ofthe louver module of the present invention and, simultaneously, sunlightis inhibited from entering into the cabinet of the heat exchanger.

The present invention, may, however, be embodied in various differentforms and should not be construed as limited to the exemplaryembodiments set forth herein; rather, these exemplary embodiments areprovided so that this disclosure will be thorough and complete and willfully convey the scope of the present invention to those skilled in theart.
